Campbell streamlined it in a way any keen-minded country artist would.
He even toured with the Beach Boys for a short while during the mid '60s. Years later, Campbell mentioned it in his own concerts.
The tumultuous years of the mid and late '70s took a toll on Campbell. The singer who learned to play the guitar at four and later lent his voice to 21 Top 40 hits, sold over 45 million records and had 12 gold records and in a decades-long career often made reference to feeling pulled between two worlds.
In a press release, Alzheimer's Association president Harry Johns praised Glen, Kim, and the rest of the Campbell family and thanked them for raising awareness about the disease. It was the pairing of a lifetime. Campbell capitalized on this popularity, and turned to television.
Recording since the 1960s, the Arkansas-born star was also known for hits Honey Come Back (1970), All I Have To Do Is Dream (1969) and his song Southern Nights featured on the popular soundtrack to this year's film Guardians Of The Galaxy Vol. 2.
Campbell couldn't resist the allure of Hollywood.
Others remembering Campbell include such diverse voices as Sheryl Crow, Kevin Jonas, Piers Morgan and Senator John McCain.
Truth be told, Campbell's work sagged during the early "70s".
"I wanted to write something that expressed to my dad how much I wanted him to feel safe. that he didn't have to worry", Ashley Campbell shared.
Here are five things you didn't know about him.
He started to sing "By the Time I Get to Phoenix" for the second time, when the band stopped playing because Campbell had previously performed the song. He was "as blonde as the sun and solid as a bale of hay", said one critic of Campbell's "beefcake physique".
"Glen just fit right in, he was so doggone good", Rumble recalls. When he was at his commercial peak, these skills were hardly in vogue-in a 2015 appreciation for the New Yorker, David Cantwell underscored how critics slighted Campbell in his prime because his hits were clearly studio creations and not "authentic".
Singer Sheryl Crowe noted that Campbell's sad death was a "huge loss in the world of music today" and former The Office actor Ed Helms posted that he was "a true gentleman genius".
